2023 Fall Semester Exam Review #2

Front

What is a solution in the context of a coordinate system?

Back

A solution is an ordered pair (x, y) that satisfies a given equation or system of equations.

Front

Identify the domain of a function.

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

Identify the range of a function.

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

How do you solve the equation -17 = 6 + a?

Back

To solve for a, subtract 6 from both sides: a = -17 - 6, which simplifies to a = -23.

Front

What does it mean for a system of linear equations to have one solution?

Back

It means that the two lines represented by the equations intersect at exactly one point.

Front

Write an inequality that represents spending time on math problems given 28 minutes for 14 problems.

Back

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input (x-value) is associated with exactly one output (y-value).

Front

What is the slope-intercept form of a linear equation?

Back

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Front

What does it mean for a function to be increasing?

Back

A function is increasing if, as the x-values increase, the y-values also increase.
